I can't figure out how to resize my image for a 16x20 image. 

I can't figure out how to resize my image to 600 px wide

I went to resize an image but the size options include cms, inches etc ... but not pixels. How do I resize to pixels, it's the most standard measurement?

I'm having the same problem. I have all the boxes checked, pixels does not appear in the size box.

I see that pixels aren't an option. I resize images for Web sites. Knowing their print size is not relevant. Only knowing pixel size is important.

ooooh, light dawns! Didn't realise you could change those top figures Duh!

Thanks muchly.

How do I resize a file from 8.78 MB down to 4 MB?

You can't resize in megabytes. You can only resize by changing the number of pixels, and as a result you will have different number of megabytes when the file is saved.

.

Of course, the idea that you need a particular file size in megabytes never makes sense, so perhaps you could tell us more about what you are doing and why you want this. Thanks.

PS: Yes, you can save (not resize) a file that results in fewer megabytes, but still this is an unusual requirement. Can you tell us more about why you want this?

See Brett's explanation above, and pay attention to the "Pixel Dimensions" readout at the top of the dialog window as you change the image size.

This is a tricky one; the good Mr DJ Paige is certainly right, you need 'Resample Image' checked, but that may not be sufficient (wasn't for me). If, even with Resample Image checked, you can't adjust the pixel sizes i.e. have no boxes in which you can OBVIOUSLY and EASILYchange the pixel dimensions, it may be that you have to delete your preferences file. Do this by holding Ctrl-Alt-Shift down as you restart PSE and agreeing that, yes, you do want to delete the preferences. Voila, pixel adjustment of image size if you have Resample Image checked. Thanks to Barbara B on the Adobe Forum, who fixed this for me. http://forums.adobe.com/message/4194940

What pixel size do I enter for an 8X10" photo print, 3750 works for a 20X30" and I tried 3000x1634 which is what it (Elements Defaults to) Whats the magic numbers ?

I have a product image of a ring on a white background. How do I resize the ring so that it is 150x150px? Each time I resize the current version, the resizing also considers the white background.

In paintbrush, I can cut the ring and paste it to upper left corner, then decrease the background manually. Is that what I need to do in PSE and if so how does that work? I've tried and can't seem to adjust background after move the product to the upper left corner.

I'm a web developer trying to learn PSE so be kind.

Yes there is and there, 3000 x 2400, with a little adjustment your on the money. Thanks for putting me in the right direction however.....

I figured it out. Basically select image, editor, image/resize and change image width to 150px with proportion constrain checked, then image/resize and change canvas to 150 x 150px and the image suddenly becomes 150x150. Then I do a file/save for web and save my smaller sized image as a jpg. Then I close the original file without saving to preserve it for other uses.

It's working for me much better than windows paint now. I really like PSE 10 and will likely buy it at end of the trial period.
